GENERAL DESCRIPTION OF THE PUMP CONTROLLER
The pump controller is attached to the pipeline that is made of thermal conductivity material and
measures the temperature of the medium in it, due to a change in temperature the voltage of 230 V ap-
pears on the output. By the pre-mounted wires any circulating pump with a voltage of 230 V or other
electrical appliance within the load capacity limits can be easily controlled.
The pump controller is responsible for turning the pump on and off at the set and measured temper-
ature, so it only operates when it is necessary. Intermittent operation saves significant energy and
increases pump life and reduces operating costs. Its digital display allows easier and more accurate
temperature measurement and adjustment than simple, traditional pipe thermostats, and makes it
easier to change modes and settings.
